A mix between the words dungeon master and masturbating. This is used in a game of Dungeons and Dragons when the dungeon master kills the party with a powerful monster then creates a powerful NPC to kill that monster. The dungeon master is essentially playing with himself.

The act of masturbating to the most fucked up shit you can find on the internet while on 20% phone battery in the toilet or outside so that when you find the material to masturbate to, your phone will run out of battery and you can only use the image that has been instilled to your mind and the fresh smell of toilet shit.
